To all whom 'it may concern:

Be it known that I, FRANCIS T. JOHNSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Clothes-Driers, of which the following is a specification.

My invention relates to improvements in clothes driers and is illustrated diagrammatically in one form in the accompanying drawings, wherein'- Figure l is a front elevation; Fig. 2 is a side elevation with parts broken away; Fig. 3 is a section along line 3 3 of Fig. 1; Fig.l #L is a section along line 4 4 of Fig. 3; Fig. 5 is a section along line 5-5 of Fig. 2; Fig. 6 is a detail fragmentary section through the front end of a modified form of drier showing a hinged doo-r; Fig. 7 is a detail of a modified form; and Fig. 8 is a detail of a modified form.

Like parts are indicated by like letters throughout the several figures.

A is a clothes drying chamber or casing having side walls A1, A1 and a rear end wall A2 and a front wall A3, the front Walls being apertured as at A4.

B, B are what I have called stoves rectangular in cross section and closed at the bottom by the baffle plates B1 upwardly and rearwardly inclined, bounded on the front end by .the wall A3 and closed at the rear end short of the wall A2. These stoves contain burner pipes B2 fed by gas from any suitable source of supply B3 controlled by any suitable means not indicated.

These stoves are supported from the walls A1 by brackets B4. Mounted above these stoves and supported in position by the brackets B5 are what I have called radiators B6 in communication with the stoves by means of the pipes B7. These radiators are comparatively large hot air chambers and are fed with heated air from the stoves B. Pipes B8 project downwardly into the radiators B6 and communicate with the interior thereof at a point adjacent the bottom. These pipes pass upwardly through the top of the radiators and discharge into one or more exhaust bays C grouped along the sides of the chamber A and supported from the walls A1. These exhaust bays communicate with the interior of the chamber A at points adjacent the bottom. They are closed at all sides and at the top and discharge through the piping C1 into the exhaust breeches C2 at the top of the chamber which in turn communicates with the chimney or flue by means of the pipe C3. It will be noted that the radiators communicate only with the center bay of each group of three through the pipe B8.

D is an intake bay communicating by means of the apertures D1 in the end wall of the casing with the outside air and discharging into the casing at a point adjacent its bottom.

D2 are intake bays communicating through the holes D3 in the front wall of the casing with the outside air and discharging into the interior of the casing at a point adjacent its top. l

D1, D4 are dampers communicating with the stoves B adapted to be controlled by the adjustable shutter D5 to control the amount of fresh air fed directly to the stove.

D6, D6 are ventilation apertures in the I top of the walls A1 protected by the downwardly depending hoods D7.

E, E1 are tracks to guide one or more racks which may be rolled into or out of the chamber A. In Fig. et I have shown two racks closed as at E2, E3 at the front and rear so that the door or opening A4 is closed by these racks when either one is in the fully opened or fully closed position.

E4, Etare screens interposed between the racks and stoves B and radiators B6 to prevent contact of the clothes to be dried with the stoves or radiators and the resultant burning.

In the modified form shown in Fig. 6, a door F is substituted for the ends of the racks E6 which door is adapted to be closed by means of a latch F1. F2 is an adjustable bottom flap adjustably mounted on the door in order to permit adjustment of the door to close it completely when the floor upon which the drier rests is not exactly level. I propose to use ordinary trucks which may be rolled into or rolled out of the drying chamber. f

The use and operation of my invention are as follows: The fire is rst lighted in the stoves, the gas being turned on and lighted as it issues from the burner pipes in the usual manner. The air in the stove will, of course, be heated and this heated air, being lighter than the cold air outside, will pass up through the connection provided into the radiator which will soon be filled with hot air. This hot air, of course, will be replaced by cooler air from the interior of the heater, which cooler air is defiected upwardly and inwardly by the deflector vanes into the stoves and toward the discharges. The air will be free to circulate in the radiator and be drawn from the bottom thereof through the exhaust pipe into one of the exhaust bays whence it will pass up to the exhaust breeches and thence to the flue. A current of air will thus be induced and toA this air will be added air drawn from the bottom of the heater' passing up through all of the exhaust bays into the breeches and thence to the radiator.

" This air will be replaced by air entering the radiator at the top through the hooded apertures, by air entering it at the bottom through the intake bay D and by air entering through the damper into the stove. By this arrangement most of the cool air will enter at the top and be drawn down gradually heated to the bottom whence it will be discharged.

l claim:

l. A drier for clothing and the like comprising a housing, a burner chamber located adjacent the bottom of the housing, said burner chamber being open along its lower side, a heat drum located above the burner chamber and communicating therewith, combined heating and exhaust chambers located along the wall of the housing, a communication from them to the bottom of the heat drum and a discharge therefrom to the outer atmosphere.

2. A drier for clothing and the like comprising a housing apertured for air intake purposes adjacent its top, a heating chamber at the bottom of the housing and open toward its bottom, hot air chambers contained within said housing communicating respectively with the heating chamber and the outer atmosphere.

3. A clothes drier comprising a housing, a plurality of heating chambers located within the housing open at their bottoms and communicating with the housing, an exhaust manifold at the top of the housing, communications therebetween and the top of the chambers.

al. A clothes drier comprising a housing, a plurality of heating chambers located within the housing open at their bottoms and communicating with the housing, an exhaust manifold at the top of the housing, communications therebetween and the tops of the chambers, heating chambers and a heat chamber heated thereby and communications therefrom to said iirst mentioned heating chambers.
